I purchased two of these bikes, one for my 14 year old nephew, and one for my 10 year old daughter. purchased it for my daughter with the expectation of the Chinese 125 cc engine being very anemic on power, I was quite surprised when I, at about 150 pounds, got on it and did wheelies through 3rd gear. The seat height kept my daughter's feet about 5 to 6 inches off the ground on both sides, so she has decided not to ride it, after two successive crashes. I have now used it a lot, and crashed it several times, for which it has held u very well. My nephew and I race them around a small track a lot, and being a sport bike and former dirt bike rider, I am not gentle. These bikes have not just surprised me, but blown my expectations completely out of the water. I have recently began to use it to teach my wife how to ride, crashes have ensued, the bike has been looped, levers have been broken, but the bike continues to persevere. These little bikes have definitely changed my opinion of the Chinese import bikes and quads, and I would absolutely purchase them again given the need for an inexpensive, easy to maintain, and reliable little bike.
